Y'know, I've always thought this. Why are we so obsessed with being in the city?Do you want to live in Wyoming, Colorado, Kansas, North and South Dakota, Montana, or Idaho?
This country has So much livable and uninhabited land. A ton of natural resources, so much knowledge to start with an agricultural type of environment (and we could eat clean ) but too many of us get caught in trying to "fight" for land that is being gentrified or has "cultural significance" where slave ancestors are buried.
We could start our own suburbs and in 100 years (if we do it right) build large pockets of this very country that are black friendly, black owned, black regulated as a start.
But the reality is that isolating yourself as a minority group generally doesnt lead to good things. Many of the states you listed have a lot of Native Americans, whom are the poorest race in the country.
